This morning I experienced a consistent 3-4 sec animation delay in a single zone in AD (greenwood or w/e that zone is called). I ported to other zones, and the delay disappeared. I completed a dungeon in that zone and experienced the same 3-4 sec anim delay throughout.
By delay, what I mean is that the action seems to have fired (there will be a buff sign on a mob or on me), but 3-4 secs would tick off before the animation would fire. Needless to say, the game is unplayeable like this.
Because the issue disappeared in other zones, I'm left to conclude that it's server side.
If anyone has any fix for this I'd be happy to hear it.
